An elastic modulus (also known as modulus of elasticity) is a quantity that measures an object or substance's resistance to being deformed elastically (i.e., non-permanently) when a stress is applied to it. We shall also learn the, Young’s Modulus Formula From Other Quantities. By definition, a stiffer material has a higher modulus of elasticity. The Young’s Modulus of such a material is given by the ratio of stress and strain, corresponding to the stress of the material. The elastic limit depends markedly on the type of solid considered; for example, a steel bar or wire can be extended elastically only about 1 percent of its original length, while for strips of certain rubberlike materials, elastic extensions of up to 1,000 percent can be achieved. The Young’s modulus is named after the British scientist Thomas Young. The constant Young’s modulus applies only to linear elastic substances. Some examples of values of the modulus of elasticity (Young’s modulus) of materials are as follows: Rubber has a low Young’s modulus of 0.01 to 0.1 GPa as it is highly elastic.
